Liberal Leader Justin Trudeau's home in Ottawa was broken into overnight, his office confirmed Saturday.

"Early [Saturday] morning, the Trudeau family discovered that their family home had been broken into. Ms. Grégoire-Trudeau and the children were asleep at the time of the incident, and Mr. Trudeau was working in Winnipeg," a statement from spokeswoman Kate Purchase said.

Everyone in the family is safe, and nobody was harmed, she added. Both the Ottawa police and the RCMP are investigating the incident.

Although The Ottawa Citizen cited an Ottawa police source saying that a note on the back patio had been left advising the owners to keep their doors locked in case of theft, The Huffington Post Canada was told the note was "threatening." A source with close knowledge of the incident described it as "very serious." Nothing, however, was stolen.
